First of all, more and more people neglect the management of their own bodies. For a long time, the physical quality of Japanese nationals has been worrying. As a developed country, Japan has high wages and great work pressure. It is common to work overtime in order to finish the task on time. 24 hours a day, except for eating and sleeping, most of the time is spent at work. Japanese people don't have enough fitness time and their physical fitness is worrying. The relevant provisions stipulate the waist circumference of citizens over 40, also because the older they are, the lower the metabolic capacity of the new city, and the more likely they are to be obese.
Second, limiting waist circumference and preventing obesity can improve citizens' physique. Talent is the foundation for a country to become stronger and stronger. Japan's small land area means a small population. In order to cultivate more talents, we must strictly manage talents. The premise that talents can play an important role is that everyone's physical quality is good. Only when you are healthy can you play a good role. Limiting the waistline of relevant personnel is also to improve the physical quality of citizens.
Third, a standard figure can represent the face of a city to a certain extent. What factors will affect the appearance of a city? In addition to related buildings, people are fundamental. For example, if a city's economy is prosperous, people walking in the street will be fat. What's your impression of this city? It will definitely be greatly discounted.
To sum up, there are many benefits of restricting waist circumference, and the prescribed waist circumference standard is also easy to achieve.
